Common causes

  • Low or worn transmission fluid
  • Faulty torque converter clutch solenoid
  • Worn torque converter
  • Valve body problems
  • Wiring

Symptoms

  • Poor highway fuel economy
  • Higher engine RPM at cruising speed
  • Shudder at 40–50 mph
  • Transmission running hot

Can I drive with it?

Usually drivable, but get it checked soon – a slipping converter clutch makes heat, and heat wears out transmissions.

Tip: A fluid change sometimes cures a shudder, but if the fluid is dark and burnt, have it inspected before driving far.

Which scanner reads it?

Any OBD2 scanner reads the basic code. Multi-system scanners can show the converter's slip speed in live data.

Budget tools like the ANCEL AD310 read it; tools with live data and graphing – like the BlueDriver or OBDLink MX+ – help you find the cause. Not sure which fits you? Try the Find My Scanner quiz.
